METAL-WHEEL MACi-IINE.

SPECIFICATION forming part of Letters Patent N 0. 653,362, dated July 10, 1900. Application filed March 30, 1900. Serial N0. 10,824. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. PAOKER, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Connecting the Parts of Wheels, of which the following is a specification.

The object of my invention is to produce a simple and effective machine, first, for assembling the hubs and spokes of metal Wheels and securing them together; second, for up; setting and forming the tire end of the spokes for such wheels, and, third, for both assembling and securing the spoke and hub and upsettingandformingthe tire endofthespoke at one and the same operation by means of the combination of cooperating parts.

In the drawings,wherein like reference characters indicate like or corresponding parts, Figure l is a side elevation of my improved machine with the frame broken away to show the construction. Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the rear clamping device or press. Fig. 4 is a side elevation of the same. Fig. 5 is a plan view of the front clamping device. Fig. 6 is a side elevation of the same. Fig. 7 isa plan viewof the middle clamping device. Fig. Sis an end elevation of the same. Fig. 9 is a side elevation of the same. Fig. 10 is an isometric projec' tion of the piston-and-lever mechanism of the middle clamping device. Fig. 11 is a similar projection of the valve-controlling mechanism of the same. Fig. 12 is a sectional view of the rear clamping-jaws. Fig. 13 is a similar view of the front clampingjaws. Fig. 14 is a side elevation of the valveactuating mechanism of the rear clamping device, all other parts being removed to more clearly show the construction. Fig. 15 is a top plan of the valve-trip of the same. Fig. 16 is a sectional view of the hub before the operation of attaching the spokes. Fig. 17 is the same hub after the operation. Fig. 18 is a section of a spoke adapted to be secured to the hub in forming a Wheel. Figs. 19 and 20 are respectively edge and side views of the free or rim ends of the wheel-s pokes after upsetting, Fig. 21 is a side elevation of alocking device for retaining the hub in proper position. Fig. 22 is a top plan of the same, and Fig. 23 is a detail view of the preferred form of ratchet device to rotate the wheel-hub.

As shown in the drawings, A is a suitable frame or bed having mounted thereon a driven shaft A, carrying at each end a wheel A or an equivalent part, provided with wristpins a? (1 A cross-head or carriage A mounted upon the bed and guided on its course by Ways a a, is connected by rods a a to the wrist-pins and is reciprocated by the rotation of .the shaft for a purpose hereinafter explained. The shaft A also carries upon it and operates eccentrics B B, which are connected by rods 1) Z) to a cross-head or carriage B, also mounted upon the bed Aand guided by the ways a a for a purpose hereinafter explained. The shaft A is driven by any preferred meansas, for example, by a belt Z and intermediate pinions X Y Y, engaging with cogs upon the periphery of the wheels A A or other equivalent meansat a desired rate of speed.

The machine is provided with three clamping devices 0, D, and E, of which 0 (called the middle clamping device) is mounted upon the cross-head B and reciprocates therewith. D (called the front clamping device) is mounted upon an adjustable crosshead F, and E (called the rear clamping device orjpress) is fixed in its relation to the bed and the other clamping devices. The two end devices might properly be called presses but in the specification and claims the rear device only is so styled, because of its particular functions.

-Referring first to the construction and operation of the middle clamping device 0, (see Figs. 7, 8, 9, 10, and 11,) it will be seen that this device comprises two opposing jaws O 0, arranged to clamp and firmly hold a spoke or equivalent member placed between them. In the preferred construction shown slides c c, retained in position by guides c c, are secured to and operate reinforcing-bars O 0 lying on the outer side" of each jaw. A longitudinally-movable rod or bar is arranged on each side of the deviceinbearings formed in the cross-head or carriage B and is provided with collars 0 0 secured thereto. Toggle bars or levers o o extend from the collars c c to the slides c c and control their movement and that of the jaws C O. A rock-shaft 0 extends transversely across the carriage and is supported in bearin gs c 0 secured to or made integral therewith. (See Fig. 8.) Crank-arms c c on the ends of the shaft engage with blocks 0 c on the rods 0 while other crank-arms 0 upon the rock-shaft are engaged by the piston-rods C O of the air-cylinders C. The compressed-air apparatus and the connecting parts are also socured to and carried by the cross-head or carriage.

The air pressure is controlled by valve mechanism consisting of suitable valves arranged in valve-chests c 0 which valves are provided with stems c c, actuated by a lever mechanism, preferably operated by hand. As shown, two bell-crank levers G 0 actuatin g the valve-stems c c, are connected by a bar 0 so as to operate in unison. One of the cranks C is mounted on a rod 0 which is provided with a lever 0 shown in dotlines in Fig. 11. A bar 0 extends from the lever c and is provided with a roller 0. A hand-lever C is provided with an arm a, which carries a cam 0 arranged to contact with the roller c, and thus longitudinally move the bar 0 to actuate the valve mechanism. It is obvious thatif preferred a compressed-air apparatus provided with a single air-cylinder may be employed.

The hand lever C is provided with an arm a", which limits the movement of the lever by contacting with stops 0 and 0 Fig. 9. A reciprocating rod E more particularly described hereinafter, is provided with a stop E which, contacting with the arm 0", serves to reverse the movement of the lever, releasing the bar 0 when a spring 0 (shown in dot-lines in Figs. 7 and 11) serves to reverse the action of the valve mechanism and returns the parts to their normal positions.

The front clamping device D is, as before w 4 5 stated, supported upon a cross-head F, ar-

ranged to permit of a limited adjustment, Figs. 1, 2, 5, G, and 13. Any preferred means may be employed to adjust the cross-head F, that shown consisting of a fixed cross-bar F, provided with threaded bolts f f, seated in suitably-threaded holes, the ends of which bolts bear against the cross-head F and determine its position relative to the fixed crossbar. The clamping-jaws comprise longitudinally-movable jaws d (1, arranged in suitable guides in a casting D. The compressed-air cylinder D is provided with a piston and a piston-rod (P, which rod at its free end engages with the block (1 carrying toggle-levers (1 (1 one of which at its outer end engages with the jaw cl and the other with the jaw d. The piston-rod is guided in the casting, as shown in Fig. 13. It is obvious that the movement of the piston-rod actuates the jaws. A cam (1 mounted on the shaft A, actuates a lever (1 pivotally connected to the bed and at its free end engaging with the valve-stem d controlling the admission of air to the cylinder D and consequently the operation of the clamping device.

The rear clamping device E, (shown more particularly in Figs. 3, 4, and 12,) which from its functions may more correctly-be called a press, is preferably fixed in its relation to the bed A, and comprises opposing jaws e e, longitudinally movable in the casting E. A block e mounted upon a bar E, engages toggle-levers e e", which extend from said block to the jaws e e, respectively, and control their operation. The air-cylinder E secured to the bed A is provided with a piston and a piston-rod 6 which impart motion to the bar E and the toggle-levers in any preferred manner. As shown, the piston-rod c engages with a pivoted lever E and actuates the same. The lever E is connected with the bar E", carrying the block 0 before referred to. The valve mechanism may be of any desired form, that shown being preferred. As shown, the valve-stem e is operated by a bellcrank lever 6 which at one end is connected with a bar a having upon its outer end a roller e. A reciprocating rod E, Fig. 14, (shown also in dot-lines in Figs. 1 and 2,) carries upon it a trip 0, secured to a bar 6 pivoted to the rod E. On its course in one direction the trip, by reason of its form, passes behind the roller e" and forces the bar e outward, actuating the bell-crank lever (2 the valve-stem c, the connecting mechanism, and the press. A spring 6 or equivalent means is employed to return the lever e to its normal position and reverse the operation. Any preferred means may be employed to reciprocate the bar or rod E As shown, Fig. 14, a bell-crank lever E supported by the bed, is connected at one end with the rod, while the other end is connected with an eccentric E mounted upon the shaft A. The action of the eccentric, therefore, reciprocates the rod as described.

The operation of my device is as follows: A hub N is placed upon a vertical shaft or stud n upon the cross-head A and is retained thereon by any preferred mcans-as, for ex ample, by a hand-screw n". The hub is otherwise retained in proper relative position by suitable means, the preferred form of which will be hereinafter described. The operator, takinga spoke 0, places it between the clamps C C with the hub end pointing toward the rear and extending between the jaws of the press E. Seizing then the hand-lever 0 he operates the air-controlling mechanism, and thus the clamping device 0, which seizes and firmly holds the spoke. The cross-head B, moving toward the shaft A, brings the outer or rim end of the spoke in proper position between the jaws (l 01. At this moment the clamping-jaws d d are operated, firmly gripping the end of the spoke 0, when the continued movement of the clamping device C, cooperating with the then-immovable front clamping device D, upsets and shapes the outer end of the spoke in a manner to facilitate the securing of the wheel-rim thereto for example, substantially as shown in Figs. 19 and 20. The clamps O O extend to a point sufficiently near the rim end of the spoke to aid in thus upsetting and forming the end of the spoke. While this is being accomplished the cross-head A bearing the hub N, has approached the press E and the hub end of the spoke, which is then in line between the jaws of the press, has by the forward movement of the carriage A been forced into the recess in the extension N, formed on. the hub for its reception. At the moment the extension N, Fig. 16, is in position between the jaws e e of the press, and while the spoke is firmly held in position by the clamping device 0 the jaws are operated, firmly gripping the extension N and forcibly pressing and bending the excess metal 12 formed on the same, into depressions or irregularities formed on the end of the spoke for that purpose, as shown in Fig. 18. The various parts are so timed as to accomplish these operations without interference with one another and preferably in the order named, the clamping device 0 firmly holding the spoke in position during both operations thereon. As the air-pressu re is automatically released by the valve mechanism the various parts of the machine are reversed, and the hub carried backward by the cross-head or carriage A draws with it the spoke O, the same passing through between the jaws of the press. Any preferred means may now be employed to shift or rotate the hub sufficiently to bring it in position for setting the next spoke. As shown in Figs. 1, 2, and 23, a weight-operated ratchet accomplishes this function. The operation described may be repeated until all the spokes are secured to the hub, when the latter, with its attached spokes, may be removed from the cross-head A another hub put in position, and the operation be repeated as desired. The rim of the Wheel is later put in position by another operation.

The means shown for shifting the hub on the shaft 17. is as follows: The pulley l, shaft 3, ratchet-pulley 8, worm-screw 4, and shaft 72. are suitably mounted on the carriage A and move therewith. The end of the band 9 engages with a suitable part on the bedas, for example, with the end 7 of the hook 6, which may be adjustably held in the bracket 5, connected to the frame. A weight 11 is attached to the other end of the band. The worm-screw 4 engages with, a suitable gearwheel secured to and operating the shaft or stud n, Fig. 23. The mode of operation of this portion of my invention is as follows: As the carriage A moves forward the shaft 01 is prevented from rotating by the locking of the hub in position, as hereinafter explained. This causes the ratchet-pulley Sto be loosely rotated on the-shaft, raising the weight. On the return motion the hub and shaft 12 are unlocked. The ratchet-pulley 8,

driven by the weight and band, engages and rotates the shaft 3 and the worm-screw 4, thus rotatingthe shaft or and the hub thereon.

It is desirable in a machine of this kind that provision be made for firmly holding the hub in proper relative position or alinement, so that the end of the spoke will be guided into the extension N. A slight displacement of the hub, so that the extension would not be in line with the spoke, would prevent the accurate assembling of the parts and seriously interfere with the successful operation of the machine. Any suitable means may be employed for this purpose, that shown being preferred. As shown in the drawings, Figs. 21 and 22, a bent or inclined spring-bar P is provided with extensions p, which embrace the extensions N when the hub is in proper position and during the forward movement of the carriage. A lever B, provided with a. roller 7', riding upon the spring-lever P, is actuated by a connection with one of the rods a, preferably by means of a bar r, connecting therewith. As shown, the end of the rod a is slotted, permit-tin g sufficient play to release the spring-bar before the end of the slot engages with the studs 1' upon the cross-head A By this construction as the operation of the machine is reversed the initial movement of the rod a depresses the spring-bar P and releases the hub from its action, after which the rod contacts with the stud on the cross-head A moving the same rearward, actuating the ratchet device and rotating the hub, as described.

The several parts of the machine are preferably made of sufficient strength to perform the various operations upon metal while cold, which when of suitable nature is susceptible of such treatment.

It is obvious that after describing my improved machine various modifications may be made without in any way departing from the spirit of my invention. Thus the several clamps may be modified as desired or to suit particular forms of work. The air apparatus may be altered and arranged as preferred or as is most convenient. Steam or other medium may be substituted for the air. The valve mechanism may be of such character as may be preferred, and the various other parts be modified as desired without in any way materially changing the functions and general purposes of the machine. Hence I do not wish to be understood as limiting myself in such respects.

Where in the claims I refer to compressedair apparatus, I wish to be understood as including steam or other apparatus operating in a substantially equivalent manner.
